Excluding parts of an electrical installation on a COC

[Isetech]

If a light fitting is secured to the building, can you fit a 15 amp plug top and excluded it on a COC?

If a cable enters a conduit buried in the ground or secured to the side of a building, can it be excluded from the COC if it plugged into a socket outlet?

If a gate motor is fed from a plug top (230 VAC, not a transformer) in a bedroom in the house, fed through a wall using a piece of 1.5 mm cabtyre buried with no mechanical protection directly in the ground, can it be excluded from a COC.

At what point is a circuit fed from a plug top excluded from the COC ?

The way I understand it, if the cable is hanging loose and the appliance is not secured to the building it can be excluded, however as soon as you secure the appliance, cabling or wireway to the building it becomes a fixture.

If the COC is required for the sale of a property, the appliance is regarded as a fixture and cannot be excluded from the COC.

The answer to your questions above are contained in 6.16.1.10
They cannot just be excluded other wise you could put a 80Amp socket outlet on the incoming mains ( if 80Amp supply ) and unplug the complete installation and just do a COC for the 1 socket



6.16.1.10 The wiring between different parts of a fixed appliance that are
installed separately is part of the fixed installation, even where it is supplied
from a socket-outlet, unless such wiring is less than 3 m in length.
Such wiring shall be protected by separate overload protection unless its
current-carrying capacity is such that the circuit protection of the socket-outlet
circuit will provide protection or that part of the appliance has built-in thermal
overload protection.
NOTE Where the length of wiring exceeds 3 m, the impedance and the functioning of
the protective devices need to be considered to satisfy the overcurrent protection
requirements in this part of SANS 10142.
